Dear Hans, I became aware of [mol2chemfig] and its fork/port to Python3, [mol2chemfigPy3] and started to think if this way: to render molecules, chemfig uses struts and cycles. Could one use this script (which already reads SMILES and .mol files a molecule editor provides) with adaptions for the similar task groff's `chem` does to accelerate/facilitate the construction of chemical structures here? A few examples of the eventual chemfig compilation with pdfLaTeX are enclosed in the .zip archive.
Best regards, Norwid [mol2chemfig]: https://www.ctan.org/pkg/mol2chemfig [mol2chemfigPy3]: https://github.com/Augus1999/mol2chemfigPy3
